Low profile cart for the insitu collection filteration and recycle of fluids from machinery

Abstract

A cart for draining, filtering and recycling oil or similar viscous fluids from vehicles comprising a wheel mounted fluid receiving chamber having a front to rear slope, handle means for positioning the open chamber beneath a vehicle, vertically disposed baffle plates positioned within the chamber to reduce movement of the fluid collected therein, drain means connected to the rear of the fluid receiving chamber and in fluid communication with a pump and filter means mounted alongside the chamber which provides pumping and filtering of the collected fluid to remove particles entrained therein and reintroduction of the filtered fluid back into the vehicle.

What we claim is: 
     
       1. A low profile cart for the collection, filteration and recycle of fluid from machinery comprising: a) a movable fluid receiving chamber having front, rear, bottom, left and right side panels forming a top opening;   b) means connected to said cart for manually positioning said cart;   c) drain means associated with said chamber and extending from said rear panel;   d) side support means outside of said chamber and connected to one of said left and right side panels;   e) said side support means having means for positioning pump and filter means;   f) means for connecting said pump and filter means to said drain means;   g) said chamber sloping from said front to said rear for permitting fluid in said chamber to be substantially and completely removed after collection from said chamber;   h) whereby when said cart is connected to said pump and filter means and said pump is activated, said fluid collected in said chamber will be evacuated therefrom and run through said filter for eventual reuse.   
     
     
       2. A cart as in claim 1 and including: a) said chamber has front and rear decks and having said top opening extending between said front and rear decks.   
     
     
       3. A cart as in claim 2 and wherein: a) said positioning means comprising a movable elongated handle connected to said front deck.   
     
     
       4. A cart as in claim 3 and wherein: a) said handle movable from a rearward, stowed position on said cart to a forward position for manually positioning of said cart.   
     
     
       5. A cart as in claim 1 and wherein: a) said left and right side panels disposed at an inward angle towards said bottom panel.   
     
     
       6. A cart as in claim 1 and further including: a) wheel means positioned outboard of said left and right side panels and adjacent said front and rear panels.   
     
     
       7. A cart as in claim 6 and wherein: a) said wheel means supported by a flange extending outwardly from said left and right side panels.   
     
     
       8. A cart as in claim 7 and wherein: a) said wheel means includes guard plates positioned forward and rearward of said wheel means.   
     
     
       9. A cart as in claim 6 and wherein: a) said wheel means positioned adjacent to said rear panels at a height less than said wheel means positioned adjacent said front panels to provide front to rear receptacle slope.   
     
     
       10. A cart as in claim 9 and wherein: a) said front to rear receptacle slope extends from about one half inch to about three quarters inch in height.   
     
     
       11. A cart as in claim 1 and wherein: a) said fluid receiving chamber is uniform in height from said front to said rear.   
     
     
       12. A cart as in claim 1 and wherein: a) said side support means is a shelf.   
     
     
       13. A cart as in claim 12 and further including: a) pump and filter means positioned on said side support means.   
     
     
       14. A cart as in claim 13 and wherein: a) said shelf including end guards for protecting said pump and filter from inadvertent collision.   
     
     
       15. A cart as in claim 13 and wherein: a) said filter is a number 10 microfilter.   
     
     
       16. A cart as in claim 1 and wherein: a) said connecting means includes a first fluid line extending from said drain means through said pump and filter to an outlet line.   
     
     
       17. A cart as in claim 16 and further including: a) valve means in said connecting means operable in a first position for opening said connection between said drain means to said pump and filter and operable in a second position to close said connection.   
     
     
       18. A cart as in claim 17 and further including: a) a second fluid line connectable to a second fluid source and to said valve so as to permit fluid in said second line to be drained and cycled through said pump and filter when said valve is shifted to a second position.   
     
     
       19. A cart as in claim 1 and further including: a) door means provided for access to and closing of said top opening and comprising a pair of doors hingedly secured to a pair of top rails extending between said front and said rear decks.   
     
     
       20. A cart as in claim 19 and wherein: a) one of said door means including a handle.
